post a pic of it if possible, if the scrapes are minor...it can be repaired, refinished and kept as a backup:D
3M Hysol or what a co-worker uses to repair plastics...wait for it...wait for it...go to the Dollar store, 99 cent store, 1 bag of green army men and a heat gun will be needed. melt one down with the heat gun and apply to the crack/scrape. let cool and sand smooth into shape. primer, paint and clear. done
something about the green army men plastic is very durable and share the same qualities as the original plastic. worth a try.
